You might have noticed that one of our contributors is quite keen on Rugby. Well, this puzzle is inspired by something read in a match report, but don't worry, it is not actually about Rugby. All that is required is logic and arithmetic.
The match report in question said that in the first half a team had three players sent to the sin bin in quick succession, and had to play three players short for four minutes.
Our contributors are special people, and this one started to think "From that information can I work out how many minutes the team played with one player short and two players short?".
So, can you work it out, and what are the times?
For those less familiar with Rugby, if a player is sin binned he or she takes no part in the game for ten minutes.
